Reinforced concrete hollow slab

Abstract

A reinforced concrete hollow slab, comprising reinforced concrete (1), a cavity component (2), the cavity component (2) is contained in the reinforced concrete (1), the cavity component (2) includes a cavity formwork (3 ), the structural bottom plate (4), the interphase cavity between the cavity formwork (3) and the structural bottom plate (4) constitute the inner rib cavity (5) of the cast-in-place structure, and the cast-in-place reinforced concrete inner rib cavity (5 ) to form cast-in-place reinforced concrete hidden ribs (6), a plurality of cavity components (2) are arranged alternately, and between each other are cast-in-place reinforced concrete main dense ribs (7), which are characterized in that the inner rib cavity (5) is provided with at least one brace (8) to connect adjacent cavity formworks (3) to each other, the cavity formworks (3) are arranged longitudinally on the same axis, and there is at least one non-prestressed or prestressed Stressed steel bars, steel wires or steel strands (11) pass through the wall of the cavity formwork (3) and the braces (8), and are connected to each other as a whole. It is suitable for the use of reinforced concrete hollow slabs, hollow floors, roofs, foundation slabs, etc.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete hollow slab. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs. This floor slab has the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid and hollow). Although the problems of earthquake resistance and cracking have been solved, a large number of templates are used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construction peri...

AI Technical Summary

Problems solved by technology

However, this kind of reinforced concrete hollow slab, because the cavity components used in it are easy to break during the process of handling and construction, the structural bottom plate is prone to breakage, and the damage rate is large, so the construction of the reinforced concrete hollow slab is inconvenient and the construction cost is high.
